Generator 37.3701: 1 - cover from the side of slip rings; 2 - rectifier block; 3 - valve (diode) rectifier block; 4 - screw for fastening the rectifier unit; 5 - contact ring; 6 - rear ball bearing; 7 - capacitor; 8 - rotor shaft; 9 - output «30» generator; 10 - output «61» generator; 11 - output «IN» voltage regulator; 12 - voltage regulator; 13 - brush; 14 - stud fastening the generator to the tension bar; 15 - a pulley with a fan; 16 - pole tip of the rotor; 17 - remote bushing; 18 - front ball bearing; 19 - cover on the drive side; 20 - rotor winding; 21 - stator; 22 - stator winding; 23 - pole tip of the rotor; 24 - buffer sleeve; 25 - bushing; 26 - clamping sleeve
The three-phase alternating current induced in the stator winding is converted into a direct current by a rectifier unit 2 attached to the cover 1. The electronic regulator 12 is combined into one unit with a brush holder and is also attached to the cover 1.
The generator connection diagram is shown in fig. 128. Voltage to excite the generator when the ignition is turned on, bring the gay to the terminal «IN» regulator through control lamp 7 connected in parallel and resistors 4. After starting the engine, the drive winding is powered by three additional diodes installed on the rectifier unit. In this case, the current through the control lamp does not pass and it does not burn. Control voltage but given to the output «6» controller directly from the terminal «30» generator. The output Ш of the regulator has no marking. A brush 18 is connected to it (see fig. 127). Brief technical characteristics of the generator:
- The maximum recoil current at 13 V and a rotor speed of 5000 rpm - A 55
- Limits of regulated voltage, V — 1-1.1±0.5
- Maximum rotor speed, rpm — 13,000
- The gear ratio between the crankshaft and the generator is 1:2.04
